There hasn't been a team tougher to figure this season than Winter Park (Fla.) High.

It has one of the best juniors in the country - Austin Rivers is No. 8 in the Rivals 150 for the Class of 2011. And it has an impressive list of victories - it is the only team to defeat No. 3 Newark (N.J.) St. Benedict's Prep and it has a victory over No. 6 Montverde (Fla.) as well as a Florida Class 6A state title.

But there are also five losses on the resume. It's the reason it began the National High School Invitational Thursday as the No. 18 team in the RivalsHigh Top 100. And the reason it has the most to gain this week.

The school got off to a good start in the quarterfinals, adding another victory over a Top 10 team by overwhelming No. 9 Arden (N.C.) Christ School, 82-72, behind 37 from Rivers.

With the victory, Winter Park advances to a semifinal game Friday against Montverde, a 51-49 winner over unranked Rockville (Md.) Montrose Christian.
